' BOTTLE CAP.

Application filed June 27, 1827. Serial No. 201,586.

My present invention relates to an improved bottle cap of the valvetype, designed for use on bottles containing I phosphates, and othereffervescent liquid beverage.

The provision of an inexpensive device of this character that mayreadily be applied to the mouth of a bottle and used as a closure,

(as well as a dispenser) to retain the pressure within the bottle, orretain the effervescent qualities of the liquid beverage or contents ofthe bottle, after the latter has 1n1- tiall of tl ie eontent's'have beenwithdrawn from the bottle.

The invention consists in a valved-head forming part of the bottle-cap,together'with elements associated therewith as will hereinafter be morefully pointed out and claimed.

In the accompanying drawings I have illustrated one complete example ofthe physis cal embodiment of my invention wherein the parts are combinedand arranged according to the best mode I have thus far devised for thepractical application of the principles of my invention.

Figure 1 is a view showing the top portion of a bottle with the cap ofmy invention applied thereto.

Figure 2 is a sectional view of the parts shown in Figure 1.

Figure 3 is an enlarged. detail sectional View of the valved-head andcap.

In order that the general relation and arrangement of parts may readilybe understood I have illustrated a well known type of bottle as 1 havingthe neck 2 and bead or with the crimped edge 5 that fits over the headof the bottle to securely hold the cap in place.

disk 6 and a layer orfilm of tin foil, as 7 is used wit the cap forsanitary purposes and to insure an air and liquid tight joint at themouth of the bottle.

Seltzer, beer,

primary object of the invention is the been opened and a portion, orportions.

of the foil Within the metal cap is retained a cork f the centralopening of the cap is riveted an, exterior head 8, which is fashionedwith an annular flange 9 surrounding the opening of the head and thishead is secured to the cap with an air and liquid tight joint also A)ouring spout or nozzle 10 extends laterally rom the head passage 11through which the contents of the )ottle may be discharged when thispassage is free of obstruction. Under normal conditions, however, thispassage is closed against exit of the liquid contents of the bottle bymeans of the circular metallic disk 12 that forms a valve or closure forthe inner end of the passage.-

The valve is fashioned with a perpendicular stem 13 that is reciprocablein the bore oropening 14 of the head 8, and a pushhead or knob 15 isprovided on the end of the stem exterior of the head.

spring 16 is coiled about thestem and interposed between the head 8andthe knob or button 15 for normally holding the valve in closedposition with relation to the passage 11.

As best seen in Figure 3, at the underside of the valve, the latter isprovided with a spur or sharpened lug 17 that is adapted to penetratethe tin foil which encloses the Valve, and initiate the tearing orbreaking that must occur the first time the valve is opened. Thus at theinitial opening of the bottle, humb or finger between the interior ofthe bottle and the passage 11 of the discharge spout 10.

tents of the bottle may have access to the' open passage, and the spur.17 insures a proper tearing or breaking of the layer. As long as thevalve is held ope f either tl 1e liquid or gaseous contents of thebottle.

Sand is provided with a seat to open communica-- this manner theeifervesoent qualities ofithe contents of the tained until-the entireconte V have been discharged.

Having thus fully bot described my 5 what I claim as new and desire toLetters Patent is The combination a bottle. cap having "a rigid head anddischargehozzle,

tle mai be minnts of the' hottle invention, secure by of a cork ing stemfor the valve,

layerlwithin the 'ca a'val ve closing said discharge nozzle anda'spring' -pressed a projecting lug'on said valve, and a sealing layerof tin foil covering said valve and cork layer.

In' testimony whereof I afiix my signature.
